In college, there was a girl (Jill) that I was interested in, but it didn't work out.

Now, ten years later, I am a successful artist who has been nominated for awards, have opened for international famous rap artists, and have "local celeb" status in my city. Been with many women and have a gf.

Over the past month, I have noticed that MANY of Jill's old college classmates (and even one prof) have begun creeping my social media a LOT. I was never friends with these people, there's no reason for them to suddenly be spying on me. She wasn't even that close to them or really in contact with them. This started VERY suddenly, and very specifically with her old college classmates.

My question is: what's going on here? Why are many of her college classmates suddenly creeping my social media?
